I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...

In the era of touch screens and capacitive buttons, we’d be lying if we said we didn’t have the occasional pang of nostalgia for the good old days when interfacing with devices had a bit more heft to ...

As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

Optical rotary encoders, sensors used everyday in industrial applications, provide instantaneous and continuous data on rotational motion. Designed to monitor speed, position, distance, and direction ...

Rotary encoders are electromechanical devices used for sensing in myriad applications—on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and ...

The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...
